I published two new papers recently! Find the titles and the links to more information below. Happy reading!

“Detecting and Modelling Structures on the Micro and the Macro Scales: Assessing Their Effects on Solute Transport Behaviour” – This paper sheds light onto a tricky issue: Is a spatial data-set stationary or not? This paper shows a method that can help to decide to delineate a boundary (“macroscale”) between regions that are at least somewhat more stationary than the entire domain. Furthermore, this paper

validates the algorithm based on a data-set where a boundary layer has previously been delineated;

demonstrates the effects of the macro structure and the smaller scale heterogeneity (“micro structure”) on solute transport behaviour; The micro structure is modelled by multivariate Gaussian and multivariate non-Gaussian structures.

“Estimating a Representative Value and Proportion of True Zeros for Censored Analytical Data with Applications to Contaminated Site Assessment” – True zeros such as no precipitation occur frequently in nature. This is one of the very few studies I know that treats those values statistically meaningfully and is based on a real-world data-set. We applied the methodology on a data-set related to contaminated sites, but this has implications everywhere else.
